Understanding heavy mineral separation duties using finite element analysis



R.A. Pax

Mineral Technologies, Queensland, Australia




Heavy mineral deposits are becoming more complex in terms of their compositional variation, particle mineralogy and size distributions, and present challenges for the operation of separation equipment to achieve the required grades and recoveries. Changes in equipment design and concepts potentially provide new opportunities for the beneficiation of heavy mineral sands deposits. The development of a framework for the fundamental understanding of separator performance issues is a first step to develop new machines. This paper will present a first step analysis of electrostatic and magnetic separation machines with their application to real separation scenarios.
